I use three examples to show the procedures for MATLAB curve fitting. Case 1: 1-dimensional distribution probability curve fitting. Case 2: 2-dimensional stress-strain curve fitting. Case 3: 3-dimensional fracture surface fitting.

I have dialy one year temperature data. I want to investigate kelvin wave. The kelvin wave investigation is original temperature minus curve fitting temperature . How can I write a code for sinusoidal curve fitting of this temperature data? the data is 3 D

Hi Shen. I have a quick question. I am a little bit confused between curve fitting and parameter estimations. Does curve fitting toolbox also recognize the parameters?

Yes, in the curve fitting toolbox, the optimized parameters of pre-defined equations will be provided.

thnks for sharing... how to import a text file data to this tool-fit.
@fuhuishen3582 жыл бұрын
I created new variables first, then copy and paste the data. You can also import a txt file data into a workspace first, then select the corresponding variables.

@@fuhuishen358 my data is made of 205 rows in cartesian coordinates (xyz). this coordinates indicate a curvature of a layer. So, i want to calculate radius of this curvature systematically.. for this layer, hyperbolic paraboloid is suitable. hyperbolic paraboloid has an equation. z=y^2/a^2 -x^2/b^2. i want to fit my data to this equation. this is my problem
